UA is trading down 13.9% at $32.64 -- and earlier hit a two-year low of $32.25 -- after issuing lackluster full-year revenue growth guidance, which overshadowed an earnings beat. Within the first 30 minutes of trading, Under Armour Inc (NYSE:UA) has seen about 18.2 million shares traded -- nearly eclipsing its current annual high of 19.5 million shares traded in a single day. The athletic apparel maker was hit with a downgrade to "market perform" from "outperform" at William Blair, and additional downgrades could be in store, with 18 of 28 analysts rating the shares a "strong buy," and only one "sell" or worse rating on the record.

SAEX is up 53.9% at $11.51, after announcing it received $24.4 million in tax credits from Alaska's Department of Revenue, and could receive up to $60.5 million in additional tax credits over the next year. To say SAExploration Holdings, Inc. (NASDAQ:SAEX) has struggled lately would be putting it lightly; the stock is down over 95% since the beginning of 2016. While SAEX's short interest is up 248.3% over the last two reporting periods, only a mere 6.3% of SAEX's float is currently sold short, which would take not even a day to cover, at the stock's average daily rate, hinting at little sideline cash available to fuel an extended rally.

DPRX is plummeting this morning, down 83.9% at $2.05, after its Locilex cream, intended to treat diabetic foot ulcers, failed to meet its goal in a late-stage trial. DPRX is now down 83% in 2016, and earlier touched a new all-time low of $1.90. There are likely plenty of bears celebrating today's sharp plunge, with Dipexium Pharmaceuticals Inc's (NASDAQ:DPRX) short interest up 35.1% over the last two reporting periods.
